Open Audit


Published on

There are many ways to keep track of your IT inventory. We have experienced great success with an Open Source solution that can automate the process of managing the inventory of a network. It can tell you what is on your network, how it is configured and when it changes. It works with Windows, Mac and Linux systems and can be customized to work in most network environments.
